Why it works: Milk and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Milk and Butter
Ingredients
Directions
Prepare
Strain unskimmed milk into a scalded churn.
Do not let the milk exceed blood heat (around 98.6°F or 37°C).
Churn
Churn daily to make butter and buttermilk.
Churn early in the morning during summer for firmer butter.
Produce butter early in the morning while it is cool.
Store and use
Scald and sun the churn immediately after use.
Use fresh butter for bread and reserve older butter for cooking.

What each ingredient does
- Unskimmed milk
- Provides the cream that separates and churns into butter, with the remaining liquid becoming buttermilk.
The step that matters
Keep the milk below blood heat. Milk that gets too warm produces soft, greasy butter that is slow to separate, because the fat stays too liquid to clump into solid grains during churning.
